GeForce 9600 GSO 384MB vs GeForce 9800 GX2

Intro

The GeForce 9600 GSO 384MB uses a 65 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR3 RAM runs at a speed of 800 MHz on this card. It features 96 SPUs as well as 48 TAUs and 12 Rasterization Operator Units.

Compare all of that to the GeForce 9800 GX2, which uses a 65 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 RAM works at a speed of 1000 MHz on this model. It features 128 SPUs as well as 64 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GSO 384MB 84 Watts
GeForce 9800 GX2 197 Watts
Difference: 113 Watts (135%)

Memory Bandwidth

Theoretically, the GeForce 9800 GX2 should perform a lot faster than the GeForce 9600 GSO 384MB in general. (explain)

GeForce 9800 GX2 128000 MB/sec
GeForce 9600 GSO 384MB 38400 MB/sec
Difference: 89600 (233%)

Texel Rate

The GeForce 9800 GX2 is quite a bit (approximately 191%) faster with regards to AF than the GeForce 9600 GSO 384MB. (explain)

GeForce 9800 GX2 76800 Mtexels/sec
GeForce 9600 GSO 384MB 26400 Mtexels/sec
Difference: 50400 (191%)

Pixel Rate

The GeForce 9800 GX2 will be much (about 191%) more effective at anti-aliasing than the GeForce 9600 GSO 384MB, and also should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce 9800 GX2 19200 Mpixels/sec
GeForce 9600 GSO 384MB 6600 Mpixels/sec
Difference: 12600 (191%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
